UNETE STATES ISAAC GEABES, OF PATRICKSBURG, INDIANA.

I MINE TOOL.

Application filed May 20, 1924. Serial No. 714,699.

To all w from it may concern:

Be itknown that I, ISAAC GEABES, a citizen of the United States,residing at Patricksb-urg, in the county of Owen and State of Indiana,have invented certain new and useful Improvements in Mine Tools, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to mine tools and more particularly to a mineblasting scraper and scoop adapted for use in cleaning the chargereceiving bores formed in coal mines.

important object of the invention is to provide a device of thischaracter which is extensible, so that it may be shortened for work inclose quarters and extended from time to time to permit its use inwithdrawing the contents of bores of considerable length.

A still further object of the invention is to provide a device of thischaracter the extensible construction of which is such that it may beemployed for making the necessary rough measurements for timbersemployed in timbering mines.

A still further object of the invention is to provide a device of thischaracter which may be cheaply and expeditiously produced and handled,which will not clog from the dirt and dust with which it is necessarilyassociated and which is a general improvement in the art.

These and other objects I attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is aperspective View of a tool constructed in accordance with my invention;

Figure 2 is a longitudinal sectional view therethrough.

Referring now more particularly to the drawings, the numerals 10 and 11indicate telescopically engaged handle portions, the section 10 being inthe form of a tube and the section 11 in the form of a small solid barclosely fitting the bore of the tube and slidable therein. To one end ofthe tube is brazed a scoop 12- curved on a diameter equal to thediameter of the hole usually formed for the reception of a blastingcharge. The free end of the section 11 is flattened and bent at an angleto provide a scraper 14 preferably circular in form and of slightlysmaller diameter than the diameter of the hole formed in such blasting.

In the construction of the device and in the formation of the scraperthe end of the tube 10 is preferably split for a short distance andforged into a semi-circular shape corresponding to the shape of thescraper which is then welded or brazed to this forged portion asindicated at 15. The rod 11 has formed therein at uniformly spacedintervals sockets 16 for the reception of the ends of a spring catch 17which projects through an opening in the wall of the tube 10 and has anattaching portion 18 forming the spring of the catch attached to theouter surface of the tube. It will be obvious that by uniformly spacingthese openings, when the latch is engaged in a given opening, theoverall length of the tool may be readily determined, thus enabling theuse of the device for rough measurements as above set forth. In cleaninga blast bore the scraper is used to withdraw such of the contents as canbe so withdrawn, the remainder of the contents which are forced to therear of the bore by the scraper being removed by the use of the scoop.

Since many changes are possible in the general construction withoutmaterially departing from the spirit of my invention, I do not limitmyself to such specific structure as hereinbefore set forth except asl1ereinafter claimed I claim 1. A mine tool of the character describedcomprising a pair of telescopically engaged handle sections, the outersection having secured to its free end a scoop, the free end of theinner section being flattened and bent at an angle to provide a scraper.

2. A mine tool of the character described comprising a pair oftelescopically engaged handle sections, the outer sectionhaving sccuredto its free end a scoop, the free end of the inner section beingflattened and bent at an angle to provide a scraper, a spring latchextending through the wall of the outer member and selectivelyengageable in sock-- ets formed in the inner member, said sockets beinguniformly spaced.

In testimony whereof I hereunto affix my signature.

IsAl-ro GEABES.
